Adjustable Wave Gauge Brackets for use with 8020
Unable to post via NIH as the uploaded files took a week to load originally**
Description of Need for Device
Dr. Parker within the ME-EM department at Michigan Tech University has had a need for components capable of adjusting the level at which the waves in the wave tank meet the wave gauges mounted above the water. Currently a block is just being rotated between the intersecting cross members, and there is still a need for individual adjustability at each bracket

Print Setup
- Models were created in FreeCAD with a 0.5 mm tolerance
- For use with a printer with a higher or lower resolution, the sketches within FreeCAD can be altered for a higher/lower tolerance
- For the prints, 1.75mm Hatchbox PLA was used with an AthenaII printer
- Settings in Cura: 0.15 mm layer height, 0.38 mm line width, 0.8 mm wall thickness, 25% infill density (grid pattern), 205 dC print temp, no build plate adhesion
- For the top slide: support was generated everywhere with a 50% overhang angle and zigzag support with a 20% density, and printed laying flat on the face with the 8020 shaped cuts as shown below. Support generates within the rectangular cut in this orientation.
- For the middle block: support was generated everywhere with a 50% overhang angle and zigzag support with a 20% density, and printed "upside down" with the extruded rectangular face touching the build plate as shown below. Support generates around the perimeter of the extruded rectangular face.
- For the bottom slide: support was generated everywhere with a 50% overhang angle and zigzag support with a 20% density, and printed laying flat on the face with the 8020 shaped cuts as shown below. Support generates between the bottom extrusion face and the plate.
- No support is necessary for the individual adjuster as long as it is printed on its largest flat surface as shown below.
